    Washing donor blood with cell salvage machines

    Apologies if this has been asked before. An interesting question from a student - if clinical staff are worried about increased potassium levels etc in donor red cell units and thus wash them through the cell saver prior to transfusion is this classed as processing units and therefore needing a specific license. I wasnít so sure as it isnít something Iíve come across before hence this post.

    Hi MJWL

    Normally use of a cell salvage process is unregulated by the BSQR, but this would be the first time I have heard of a blood component being washed in a cell salvage prior to transfusion. I will highlight this to an inspector for a response.

    Gosh I don’t know how that would work practically. Why not issue fresh units?

    Best practice would be to issue fresh but if all the “fresh” are now depleted and moving onto “less fresh”

    Hi MJWL

    You will appreciate that since this original post our GMP inspectors have had more pressing matters to deal with, so in lieu of an official answer, I would go with my original answer and say that using a blood component in the way described would be classed as a processing step and would require that site to have a Blood Establishment Authorisation that specifically mandates that process. So, another way of saying it would be that cell salvage machines should never be used to process a blood collection.

    As the question was theoretical, I feel confident to say that, but if I'm wrong I will let you know here.

    Hi MJWL,
    It would be interesting to know the hypothetical scenario we are talking about-what is the reason for the patient requiring blood with a lower K+ level?
